It features a single-core 32-bit RISC-V processor at up to 240 MHz, dual-band WiFi 6 (2.4/5 GHz), Bluetooth 5.0 LE, and 802.15.4 support for Zigbee/Thread/Matter. Despite its tiny footprint, it exposes up to 19 GPIO pins via standard headers and an FPC connector, includes USB-C for power and programming, and supports 3.7V battery charging. Two variants are available: the standard Stamp-C5 ($6.50) and the Stamp-C5 DIP ($7.95). It is currently the smallest ESP32-C5 USB-C board available, edging out the XIAO ESP32-C5 and NiceMCU ESP32-C5 Mini in size while offering more I/O options. ## Full article daily.dev links to this article rather than hosting it.
